Re: gun for my wife
If she is OK with recoil and a brake is OK, then just about any rifle will work.
The weight of the rifle will make a large difference in felt recoil, and some rifles won't require a brake.
A simple .243 Winchester is a fine rifle as long as ranges are kept to a minimum. The recoil isn't bad at all. I actually have a .243Win Rem 700ADL that was cut down for a lady about the same size as your wife. It was used for Antelope and Mule deer for several years in the late '70's. I'm sure it would work just as well today.
With the increasing focus on Bigger - Bigger - Bigger, the old .243 gets a bad rap.
There are other calibers that come to mind. 25-06 is a GREAT caliber for your needs, with an appropriately balanced rifle (a little shorter stock and a little heavier barrel) the recoil would be fine for a hunting rifle.
There are dozens of other cartridges that could be made to fit the requirements. 7mm-08, 280Rem, 6x284, 270, 6.5x284, 6mm Rem etc etc
I'd probably take a long look at a 25-06 with a little heavier than normal barrel contour at around 24" long and a laminate stock. End up with a rifle between 9 and 10 lbs with scope and the recoil would likely be very manageable and the range and killing power more than adequate for the animals you listed.
If some is good and more is better, then too much is just right.
My mind is a raging torrent, flooded with rivulets of thought, cascading into a waterfall of creative alternatives
